Job Description

Wat ga je doen?

A first student internship assignment was performed where the effect of a shock on a simple cantilever leaf spring was studied by (1) pseudo velocity – stress relationship (2) Ansys SRS analysis (3) Ansys transient analysis and (4) experiment. Follow-up questions are: 

  • Extend the existing analyses to a construction that is closer to an actual device construction: is the “pseudo velocity – stress relationship” theory still valid? (e.g. different cross-sections and multiple materials)
  • Comparing different shocks: can we confirm that the shock with the highest pseudo velocity gives the highest stress? And from what level is a shock severe for typical Demcon equipment?
  • What is the effect of an initial load/deformation on the stress due to the shock?
  • How can we perform shock analysis for multiple degree of freedom systems? (e.g. a base unit that is mounted on a trolley with a relatively low eigenfrequency)
  • Ready to Apply?
